WATER MOTOR.

Application filed November 1, 1926. Seral No. 145,622.

My prestant invention relates to improvements in water motorsof the endless chain type adapted to be supported upon a float, and provided with spaced paddles to receive power from the flowing stream as from water in a swiftly 1noving river.

The primary objeCt of my invention is the provision of a power plant or water motor of this type by means of whioh power may be developed and transmitted to the place of use, for numerous purposes. Means are provided for unshippingthe paddles or blades carried by the endiess chains and v supported on the float, in order that the 1notor may be rendered inoperative. The invention consists in certain novel combinations and arrangements of parts as Will be hereinaiter more fuily pointed out and claimed.

In the 'accompanying drawings, 1 have illustrated one complete example of the physical embodiment of my invention wherein the parts are co1nbined and arranged according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a top plan view of a water motor embodying my invention;

Fig. 2 is a longitudinal sectional view of the motor in Fig. 1;

Fig. 3 is a transverse, vertical soctional view, enlarged, at line 33 of Fig. 2; and

Fig. 4 is a broken perspective view of a blade in unshipped position, together with part of the unshipping mechanism.

In carrying out my invention, I preferably use a pair of spaced buoyant floats or pontoons as 1 and 2 between which a channel is formed for the operation of the water motor. The pontoons are connecter] loy cross braces as 3 and decks as 4- are fashioned on the pontoons in usual manner.

A pair of endless chains 5 and 6 having sprocket Wheels as 7 and shafts 8 and 9, in bearing;s 10, are provided for operating the water inotor. The two shafts are located at opposite ends of the pontoons or floats, and the endless chains extend longitudinally of the fioat as indicated in Fig. 1. The shafts 8 and 9 are supported above the top of the float, and the endless chains on the sprocket wheels of the shafts are provided with a suitable number of transversely arranged, rectangular blades or paddles 11, fashioned of smtahle material. These blades are Hrngged. at 12 to cross rode 1.3, and the eteae rods are attached at 14 to the chains, in order that the biades may be suspendecl in vertical position perpendicular to the lower flight of the chains, for a working stroke, and in idle position the blades are adapted to lie fiat on top of the upper fiights of the endless chains as they return to working position. On the ends of the cross rods 13 are provided rollers 15, and these rollers roll over 01' ride on angle irons 16 which form cracks for the perpendicular blades when in working position. These tracks or angle irons are attached to the adjoining inner sides of the two pontoons above the water line, and the rollers 15 roll over the. flange of the angle iron and are retained against displacement by these angular tracks.

Each blade is provided with a presser roller 17 journaled in a bracket 18 carried by each blade and secured to the blade at its central 1ine. W'hile the blade is traveling in operative position as indicated by the arrows in Fig. 2, the guide rollers or presser rollers 17 travel along an overhead guide board 19 which extends longitudinally of the 1notor and is provided with curved ends 20 and 21. In Fig. 2, it will be seen that the blades flop over to horizontal position as they travel around the shaft 9,when the presser relier 17 of each blade encounters the curved end 21 of the guide board 19. The blade is thus caused to swing around the shaft 9 as an axis, and as it reaches a position for impact by the flowing stream, the blade is brought to vertical position With the presser roller 17 .engaging fthe track 19 and resisting the pressure 01: the water applied to the blade. The blade is thus held in position to receive pressure irom the water and such pressure moves the blado in manner Well understood.

The return flight of the endless chains is supported. by a pair of overhead tracks 22 and 23 located above the shaits 8 and 9 and in position for the rollers 15 on the ends of the cross rods 13 to roll along. The blades lie fiat when traveling along the idle flight of the chains as indicated in Fig. 2.

The pressure of water against the blades of the working fiight of the chains operates these chains, and through the sprocket wheels the shaft 8 is rotated. This shaft is provided with a drive pulley 24 and a boit 25 from this puli ey extends to a pump pulley 26, ""i'mp is indicated at 27 and the dimalir!t pipe tf1om the pump is indt= cated at 28. The ntility of the watenmotor is thus indioated, but it Wll be understood that the power derived therefro1n may be applied in diif'orent ways and for diflerent purposes.

Vl1en the motor is not required for use, the blades are unshipped, -thatis, moved to inopeativo position along the working flight of the endless chane. In Fig. 3, it Will be seen that each of the l)lades is pro vided with a pair of cutont corners as 29 to allow the unshipping plates to be set to render the motor inoperative. Beneath thetracks:16- for the rollers 15 are snspended a pair of fiat plates 30 and 31 which are. hinged at 39 to the nnder sides of the tracks 16: When the.motor isin operation, these plates 30, 31 bang in vertical position as indicated by full lines in Fig. 3, and do not interfere with the movement of the passing blades. To nnship the blades, these two fiat plates are turned up in horizontal position as indioated b y dotted limes inFig. 3. For this purp0se, aaoperating lever 33 is employed -which is pivoted at 34 to a suitable support onthe float, and a link position are:free to passto the rearof the fioat,; but succeeding blades, asthe oneat the right end in Fig. 2, as they swing around the shaft 9, are prevented from assuming operative position; As the outer free edge of the blado encountcrs the two plates 30 and 31, the blade is held against tnrning, and the roller 17 is pul1ed away from the guide board 19. The l1lado is thon 11nsl1ipped as indieated in Fig. 4 and travel. along to the rear of (lie n1otor, outil all of the blades onlhe working fli;rht are turnml into inoperative position. In this position, the blades are all l1old ahove 111e water lino, and out of the,wa y ol driitwood or otl1er dbris fioating down the stroa1n. To slart theanoto1, thelever 33 is opemted to.swing theplates30 and 31 t0 vertical position. Then the horizontal bladeson the lower or working flights 0'E the chane are free to swing dowhwardly to receive pressure from the water, and the:motor is started.

Having thus fnlly.described my inven (ion, what I clai1n as new and desire to cure hv Letters Patent, is:

1. Tlle combination in a water motor ol a pair of' endless chains and transrereoly arranged blades carried thereby, oI fixed traoks and rollers carried by the blades supported onsaid traeks, 21 pair of unshipping plates normally in inoporatiw position, and means for moving said plates t0 operatire position for unshipping the blades of the worlcing flights olthechains.

2. The combination in a water n1otor =in clnding endless chains and -blades earried thereby, of a pair of hinged spacod plates, means for swinging said hinged plates to horizontal position to form tracks .fo1: unshipped blades, andsaidwblades having means topermit operation of those unsl1ipping plates.

8. The -oombination in a water n1otor With a pair of endless chane and.blades on said chains having;cntout corners, o:E a pair of spaced hinged unshipping,platcs each l1aving alever arm secured thereto, a link connectingsaid arms, an operating lever, and a link connecting;psaid lever with one of tlxe lever arms.

In testimonywhereof I aflix mysigna tare.
